Web22 de sept. de 2007 · We study bounded ancient solutions of the Navier-Stokes equations. These are the solutions which are defined for all past time. In two space dimensions we prove that such solutions are either constant or functions of time only, depending on the exact definition of admissible solutions. The general three dimensional problem seems to … Web4 de oct. de 2024 · Quantitative partial regularity of the Navier-Stokes equations and applications.

Skip to main content Accessibility help We use cookies to distinguish you from other users and to provide you with a better experience on our websites. The Navier–Stokes equations are partial differential equations which describe the motion of viscous fluid substances, named after French engineer and physicist Claude-Louis Navier and Anglo-Irish physicist and mathematician George Gabriel Stokes. They were developed over several decades of progressively … Ver más The solution of the equations is a flow velocity. It is a vector field—to every point in a fluid, at any moment in a time interval, it gives a vector whose direction and magnitude are those of the velocity of the fluid at that point in … Ver más Remark: here, the deviatoric stress tensor is denoted $${\textstyle {\boldsymbol {\sigma }}}$$ (instead of $${\textstyle {\boldsymbol {\tau }}}$$ as it was in the general continuum … Ver más The Navier–Stokes equations are strictly a statement of the balance of momentum. To fully describe fluid flow, more information is needed, how much depending on the … Ver más Nonlinearity The Navier–Stokes equations are nonlinear partial differential equations in the general case and so remain … Ver más The Navier–Stokes momentum equation can be derived as a particular form of the Cauchy momentum equation, whose general convective form is where • $${\textstyle {\frac {\mathrm {D} }{\mathrm {D} t}}}$$ is … Ver más The incompressible momentum Navier–Stokes equation results from the following assumptions on the Cauchy stress tensor: Ver más Taking the curl of the incompressible Navier–Stokes equation results in the elimination of pressure. This is especially easy to see if 2D Cartesian flow is assumed (like in the … Ver más WebSection 4: Examples Using the Navier-Stokes Equation In general, these equations are handy to have as they establish a starting point for going about modeling fluid flow. When it comes to analytically deriving models (as in using pen and paper), it is orders of magnitude more diffucult when you deal with fluid that move in more than one direction. python or javascript
